AGC运行时一种保生态下泄流量功能设计与实现

The design and implementation of the function of ensuring the ecological discharge in AGC operation

摘要:

本文针对目前水电站AGC运行时最低下泄流量控制的新需求，充分考虑了水电站普遍实行远方集控的实际情况，逐层剖析了水电站保生态流量功能设计时主要需要考虑的因素，较为深入的对各因素进行了重要性评估和优化近似处理，提出了一种基于电站计算机监控系统的保生态流量功能设计方案，该方案有利于推动新环保要求下水电站AGC功能设计与实施，并在大渡河猴子岩水电站取得了很好的效果。

Abstract:

Aiming at the new requirements of controlling the minimum discharge flow in hydropower stations during AGC operation, the actual situation that hydropower stations commonly implement remote centralized control is fully taken into consideration, and the major factors that need to be considered in designing a hydropower station with the function for ensuring ecological discharge are analyzed. The importance of each factor is evaluated and the approximate processing is optimized. At last, a new strategy of designing the ecological flow protection is proposed based on the computer monitoring system of hydropower stations. The strategy is proved to advance the design and implementation of AGC function in hydropower stations considering the new requirements of environmental protection, and shows a good performance when being applied to Houziyan hydropower station located in Dadu River Basin
